Big Brother has designed this house in such a way to promote the lies and deceipt etc.
The posters in the house that say deceipt, cheat, loyalty - etc. are not there just by chance. Heck, they even had a HOH comp on based on those posters. If anyone thinks this is 100% true to life, they are sadly mistaken. It is a TV show, there are things that are done in the house strickly to promote clashes. It is all part of it.
I am not saying I agree with how everything is going down, but I certainly am not going to condemn them for playing the game. No matter how you look at it, it is still just playing the game. Some of these people actually had friendships outside the house prior to the game, however most of them were playing as if they never met each other as the game started. And you don't think that was pre-planed - please. It's TV. This show is for pure entertainment value and should not be taken so literally, as some people have been doing. If people cannot handle the "reality" of the show, maybe they should not watch.
And as far as Janielle is concerned, she has done her share of lying and deceipt just as everyone else has. Howie himself caught her in a lie and called her on it. She is not a saint in all of this. But then again, she was just playing the game - just not very well.
